Hi guys,

I currently drive a BMW M135i and I'd like to get it dropped by around 20-30mm for a better look.

I've currently received 2 quotes, one is for new springs from Hi-Q for R4000 that apparently rivals H&R springs and another for R3000 to press my springs from a different tyre shop , and according to the salesman compressing the springs gives me a softer ride but I'm scared it scrapes against the tyre and isn't good for the cars suspention.

Which one should I opt for? Any help would be appreciated greatly, thanks guys.

So take a perfectly awesome car and go **** it up to "look better" (which it doesn't by the way).

Sorry I can't be party to this...

None of this is good for the car, German engineers did all the work so stick to their hard work and the huge amount of money you already paid for it instead of putting some cheap **** in place to negate it.

Probably neither- in all honesty I can't see how people would want to lower their vehicles, considering the state or our roads in general.


Having said that, option one, I can see no good coming from compressing your stock springs in a way it was never intended to be done. Just research this spring option that supposedly rivals H&R springs. I know Eibach springs are also popular. Also maybe ask on the BMW fanatics forum?

You're going to ruin you ride and handling if you go with any of the above-mentioned. Do it right or don't do it at all. Save up for some KW coilovers.

We had a guy at work who lowered his polo so much that you couldn't fit your shoe under the sideskirts. He was always replacing front bumper parts and crawling over every little bump in the road, I would much rather fit my polo with All terrain tires and jack the suspension up a meter or so to go as fast as possible over the bumps, but that's just me XD

^^^ agree wholeheartedly with this,

lowering a car ruins it, as this video will suggest,

[video=youtube;Zk6WEihO-Dg]https://www.youtube.com/watch?v=Zk6WEihO-Dg[/video]

also as somebody the victim of such a car crime, not fun driving around a car with lowered suspension,
tires get chewed up, fuel economy goes through the roof,
and with the state of the roads lately, you going to suffer terribly with that idea.

the car was designed that way by engineers, to be perfect in all conditions,
messing around with that causes more issues than it fixes.

Where are you located?

You drive a high performance car. You should be using performance aftermarket springs or coilovers if you want to lower your vehicle.

Personal taste bud, I didn't ask if you like it or not.

I could spend a few grand more and get H&R's from the same guy ( The reason I'm asking because I wanna wrap the car aswell and wanted to see if I could save few rands ), but I wanted to see if the above mentioned would negatively effect the car , I appreciate the answers that actually helped and i've noted the above.

Others trying to tell me it wont like nice can bugger off.

1) Don't do it because you are far more likely to break what is an awesome and perfectly optimised piece of machinery.
2) If you don't care about reason, then you should look at maths, not what the car salesman tells you. I highly doubt you or the car salesman have done the maths looking at oscillations and dampening that the ride quality and handling depend on. From a theoretical point of view and assuming your cars suspension is behaving like a linear system, the only thing you need to match is the spring and dampening constants with the ones that are already on your car. In the strictly linear zone of travel (aka normal usage), if you matched them up there would be very little difference in ride comfort or handling.
I highly doubt the springs you have gotten quotes on or the guys from the tyre shop are going to be taking into such things into account.

If someone wants to make an 80 degree turn to drive over speedbumps while going 1 km an hour, who are you to interfere?
By all means.

People have this perceived idea that it looks good, handles better and and and. None of it's true. But it's his car, he can do as he pleases won't affect me at all, not my car or my money :D Was just giving him some adult advice.

Are you prepared to stand patiently behind him while he owns the two lanes at the speed hump?

If you do it, dont cut corners. Get the best kit you can afford and forget about compressing/cutting your existing springs. Look at Koni , H&R or Eibach.

Was thinking those shocks she mentioned were on the cheap side for a BMW

I have a 320 and it's already pretty low standard. I can only imagine how low a 135 is and then lowing it more... Fark no!
